Bill and Steve are enjoying a beer and discussing the possibility of love.
"I thought I was in love three times," Bill says.
"Thought?" Steve asks.
"What do you mean?" "Three years ago, I cared very deeply for a woman who wanted nothing to do with me," Bill says.
"Wasn't that love?" Steve asks.
"No, that was obsession," Bill explains.
"Then two years ago, I cared very deeply for an attractive woman who didn't understand me." "Wasn't that love?" asks Steve.
"No, that was lust," Bill replies.
"And just last year, I met a woman while I was on a cruise.
She was gorgeous, intelligent, a great conversationalist and had a super sense of humor.
Everywhere I followed her on that ship, I would get a very strange sensation in the pit of my stomach." "Well, wasn't that love," asks Steve.
That was motion sickness!" Bill replies.
